Blakeeae (Melastomataceae) are a Neotropical tribe of mostly hemiepiphytic woody plants that frequently form domatia harboring mites or ants in mutualistic associations. The tribe comprises 10 species in Chalybea and Huilaea and nearly 200 species in Blakea and Topobea. Key characters separating the latter two genera pertain to anther morphology; however, numerous species have been discovered with intermediate anther forms, thus making an already dubious distinction even more doubtful. In order to test the monophyly of Blakea and Topobea, we conducted three phylogenetic analyses using 111 morphological characters, partitioned into qualitative, quantitative, and combined data sets. These analyses resolved the genera as polyphyletic. Blakea has nomenclatural priority; thus, Topobea must be synonymized. Morphological character evolution tracked on the combined cladogram demonstrates the phylogenetic utility of these 111 characters, as many are synapomorphic for particular radiations within Blakea.
